I have this situation
laptop connected to server, O: server hard drive
On the road
I copied all of O: content to D: on my laptop, now most programs stil refer to O: in stead of D: and I cannot change all of them. So I created a network connection O: that points to D: on the laptop (with a different user)
The network connection only works when I connect to a network (any network), when not connected at all I only get media disconnected and network connection doesn't work at all.
